I've put 6,500 miles on this car over the past 6 months and have been very pleased. It replaced a Lexus LS430 and an older Volvo V70. The ride quality is smooth and quiet. While I really enjoyed the super-quiet ride and precise handling of the Lexus, I am also enjoying the sportier driving experience of this Volvo. I much prefer this car to the roughness and sway of the SUV's I have owned. Based on the car's computer readout, fuel mileage is considerably better than the EPA numbers (30 - 32 MPG at 60 MPH). Build quality seems good with no significant problems so far.
Personal Car Communicator/keyless start, power lift gate, blind spot information system, Volvo towing package (expensive but worth it)
Rubber bumpers between body and lift gate tend to squeak (occasional WD-40 stops it), Sirius radio loses signal in wooded areas
